General Description

The CX-2V quartz crystal is a high quality tuning fork resonator

designed for use in Pierce (single inverter) oscillators. The CX-2V is

hermetically sealed in a rugged, miniature ceramic package, a

quarter the size of an eight pin dual-in-line package. The crystal is

manufactured utilizing a photo-lithographic process, ensuring

consistency and repeatability of electrical characteristics.

Full military environmental testing available

Package Handling

The CX crystal is hermetically sealed in a ceramic package.

Normal handling and soldering precautions for small, low thermal

mass parts are adequate when installing or testing CX crystals.

The crystals may be wave soldered, taking proper precautions to

avoid desoldering the leads. A slow machine rate or too high a

pre-heat temperature or solder bath temperature can damage the

crystals. Lead to package solder interface temperature should not

exceed 175°C, and glass lid to package seal rim temperature

should not exceed 210°C. Should the seal rim temperature exceed

these limits the package may lose its hermeticity. Loss of

hermeticity results in a decrease of frequency and increase in

motional resistance.
